Different from the J/psi yield which is almost identical at SPS, RHIC and LHC energies, the J/psi transverse momentum distribution is sensitive to the nature of the medium and can be used to probe the quark-gluon plasma formation in heavy ion collisions.  We calculated in a detailed transport approach the nuclear modification factor, the averaged transverse momentum, and the elliptical flow of J/psi mesons at RHIC and LHC energies.
